This chair is very comfortable; has several positions for the back. Very good buy especially considering the price. It may not be the most aesthetically pleasing but very comfortable.
This is a smart looking desk chair that is ergonomically designed to be easy on your back. It has several places that can be adjusted to fit your specific needs. I would have given it 5 stars but I had a little trouble putting it together. It wasn't hard but screwing the back onto the base was heavy and awkward. I did it by myself. If you have help it's probably not an issue.
My biggest concern with office chairs is always how well the chair moves around with the wheels. Excellent on that course and the adjustability of the chair (arms back support height etc.) is also a huge benefit.
